Hybrid transcoding for adaptive transmission of 3D content

For traditional multimedia types, transcoding has proven successful in serving variations of the same object at different sizes and using different modalities. Transcoding, which is defined as a transformation that is used to convert multimedia content from one form to another [1], can be naturally extended to 3D data. By their very nature, 3D models are amenable to access through various representation modalities that typically imply trade-offs between complexity, interaction, and download times. In this paper we describe the design and development of an adaptive environment for rendering of 3D models over networks. This environment monitors the resources available and selects the appropriate transmission and representation modalities to match these resources.
